What is break-even ROAS and how do you calculate it?
Break-even ROAS is the return on ad spend at which ad-driven sales just cover product costs and ad spend, leaving no profit or loss. It is an industry term, not a Meta metric. A common calculation is 1 divided by your gross margin: at a 40% margin, break-even ROAS is 2.5.
Break-even ROAS = 1 ÷ gross margin (as a decimal)
A ROAS figure only becomes a decision once you know the line it has to clear. That line is break-even ROAS: the point where the gross profit from ad-driven sales exactly pays for the ads. Above it, the ads add profit; below it, they lose money even if the ROAS looks healthy. This is an industry term, not a Meta metric, so you calculate it yourself from your own costs.
How do you calculate break-even ROAS?
Divide 1 by your gross margin, written as a decimal. Gross margin here is the share of each sale left after the cost of the product, and any other per-order costs you choose to include.
| Gross margin | Break-even ROAS | Sales value needed per $100 of ad spend |
|---|---|---|
| 80% | 1.25 | $125 |
| 60% | 1.67 | $167 |
| 50% | 2.00 | $200 |
| 40% | 2.50 | $250 |
| 25% | 4.00 | $400 |
Every figure in the table is arithmetic. At a 40% margin, $250 of sales leaves $100 of gross profit, which exactly pays $100 of ad spend.
Why does Meta call a ROAS of 1.00 break even?
In its ROAS goal guide, Meta writes that a ROAS goal of 1.00 is break even: spend $100 and get around $100 in purchase value. It describes anything above 1.00 as profit, with 1.15 meaning about $115 of purchase value per $100 spent.
That example compares only ad spend and purchase value. Product, shipping and other costs are not in it. So Meta’s 1.00 is the point where recorded revenue equals ad spend, while a margin-based break-even is higher whenever your margin is below 100%. Meta’s own advice is to set your ROAS goal based on the return your business needs to stay profitable.
How do you use break-even ROAS in Meta Ads Manager?
- Work out your gross margin per order from your own cost data.
- Divide 1 by that margin to get your break-even ROAS.
- Compare it with purchase ROAS for the same date range and attribution setting.
- Treat ad sets below the line as losing money on first purchases, before any repeat orders.
Meta’s purchase ROAS divides purchase conversion value by amount spent, and Meta says some events and their values may be statistically modeled. Your break-even line is exact; the ROAS you compare it with may not be.
Should you set your ROAS goal at break-even?
Meta’s starting-point advice for a ROAS goal is based on your own history:
- Express the goal as a number between 0.001 and 1000.00.
- Start 10 to 20% below your average historical ROAS, based on results within your attribution setting.
- With no history, run highest value bidding for at least 2 weeks and use the resulting ROAS as the starting goal.
Your break-even figure tells you where profit starts. Meta’s starting point is meant to give the delivery system room to optimize. When the two differ, you decide which matters more for that campaign.
FAQ
Can I see break-even ROAS in Ads Manager?
No. Meta’s ROAS metrics divide conversion value by amount spent and include no product costs. Break-even ROAS is an industry term, not a Meta metric, so you calculate it from your own margins and compare it with Meta’s reported ROAS.
Do discounts change my break-even ROAS?
Yes. A discount lowers the revenue per order while the product cost stays the same, so the gross margin falls and 1 divided by the margin rises. A 20% discount on a product with a 50% margin cuts the margin to 37.5% and lifts break-even ROAS from 2.0 to about 2.67.
Should I include shipping and fees in my margin?
If you pay them on every order, including them gives a more honest line. Each extra per-order cost lowers your margin and raises the break-even ROAS. Use the same cost definitions every time so the figure stays comparable from month to month.
